Abstracts Floristic Letters 42 (2008)
Abstract: Selected new records, confirmations and recent losses in the vascular flora of the city and county of Göttingen (Southern Lower Saxony, Germany) are reported. New findings mostly concern alien species (neophytes; adventive trees and shrubs are excluded). Neophyte records include taxa with remarkable population dynamics or which have, as yet, been rarely reported from Central Europe (e.g., Adiantum raddianum, Allium giganteum, Euphorbia serpens, Iris sanguinea, Leptinella squalida, Muscari aucheri). Indigenous species records include the rediscovery of Equisetum pratense, believed to be extinct in the area for more than onehundred years, and new stations or confirmations of other rare or declining species (e.g., Lathyrus niger, Leersia oryzoides, Salix repens, Trifolium fragiferum). While many formerly common or frequent species seem to be further declining, their present status in the area remains often uncertain. Probable recent extinctions are inferred or specified for a few species. Taxonomic or nomenclatural remarks are annotated for some taxa including Eragrostis pilosa, Euphorbia virgata, Hylotelephium (Sedum telephium s.l.) and Muscari.
Keywords: Vascular plants, neophytes, Göttingen, Lower Saxony, Germany.
FUCHS, R. & KEIL, P., Die pflanzengeographische Bedeutung der Wälder im westlichen Ruhrgebiet (Nordrhein-Westfalen), S. 60-76
Abstract: Phytogeographical significance of woodlands in the western Ruhrgebiet. The western Ruhrgebiet is located in the border area of the three ecoregions “Süderbergland”, “Niederrheinisches Tiefland” and “Westfälische Bucht”. Some relicts of semi-natural ancient forests with a lot of chorologically remarkable taxa document the phytogeographic importance of this region. Some of these taxa are presented and discussed.
Keywords: Ruhr area, ancient forest, phytogeography
GARVE, E. & ZACHARIAS, D., Ein Fund von Chorispora tenella in Südniedersachsen, S. 77-82
Abstract: Purple Mustard (Chorispora tenella) in Southern Lower Saxony. A neophytic occurrence of Chorispora tenella (family Brassicaceae) is recorded in 1998 and 1999 colonising a disturbed area in Hildesheim-Drispenstedt (Lower Saxony). The vegetation with Chorispora is documented by relevés in both years.
Keywords: Purple Mustard, Mustard family, Brassicaceae, flora, neophyte, Lower Saxony, ruderal site
WEBER, H. E., Eine neue Rubus-Art mit montaner Verbreitung in Westfalen, S. 83-92
Abstract: The new bramble species Rubus haeupleri (ser. Glandulosi) is described. It belongs to the Rubus hirtus group because of its dark-violet long-stalked glands. Its known distribution area reaches in the sub- to high-montane zone of Westphalia (NW-Germany) from the southernmost "Süderbergland" to the Weser-Bergland. It is named after Prof. Dr. Henning Haeupler (Bochum).
Keywords: Rubus, Glandulosi, batology, Westphalia, brambles, taxonomy, new species
BÖHLING, N., Drei Pflanzenarten neu für Deutschland, S. 93-100
Abstract: By the way: three new plant taxa for Germany.
Occurrences of three taxa new for Germany are commented on: Syringa komarowii subsp. reflexa (C.K. Schneid.) P. S. Green & M. C. Chang from China, Arabis nova Vill., a S European orophyte, and Medicago sativa L. s. str.
Keywords: Syringa komarowii subsp. reflexa, Bogenflieder, Arabis nova, Felsen-Gänsekresse, Medicago sativa s. str., Echte Luzerne, new records, neophytes, climate change, biodiversity
DIERSCHKE, H., Harz, Schwarzwald und Vogesen – gibt es eine subalpine Vegetationsstufe in den Mittelgebirgen?, S. 101-118
Abstract: Harz, Black Forest and Vosges – does a subalpine vegetation belt exist in the Central European mountains?
Today there is agreement on the basic altitudinal zonation of vegetation in Central Europe, with a planar, colline, montane, alpine, and nival belt (with further subdivisions). Rather obscure, however, is the definition and the associated vegetation of the subalpine belt. By example of the Fimber Valley in the Central Alps the vegetation mosaic of this belt is explained. Unforested summit areas of some other high mountains with an extreme local climate are also referred to as subalpine. The floristic and vegetation analysis of the Brocken (Harz Mountains), Feldberg (Black Forest) and the Upper Vosges shows indeed the appearance of glacial plants and plant communities of subalpine character. However, the characteristic prostrate scrub (krummholz) with Pinus mugo and Alnus viridis is completely missing. Besides, the summits are severely affected by human activities since a long time. Therefore it is proposed here to term this zone above the upper montane belt as supramontane belt.
Keywords: glacial plants, climate, plant communities, supramontane belt.
SCHMITT, T., Mikroarealophyten auf Mallorca – Diversität und Gefährdung. Ein Nachtrag zu einem Aufsatz von Henning Haeupler, S. 119-132
Abstract: Microarealophytes on Mallorca – diversity and threats. A follow-up to an article of Henning Haeupler.
A flora census of vascular plants on the Mediterranean island of Mallorca provides evidence that microarealophytes have a 9.4% proportion of the island’s vascular flora. Microarealophytes are an important qualitative characteristic of the island’s phytodiversity, which is spatially unevenly distributed. The focal points of microarealophytic occurrence are the high altitude areas of the Serra de Tramuntana in the Northwest and the cliff coasts. Compared to HAEUPLER’S (1983) first account of microarealophytes on Mallorca our research shows an increase in the number of taxa, resulting mainly from the differentiation of the genus Limonium with its numerous local endemics. Due to the extremely small distribution areas on the cliff coasts, these local endemics are highly endangered.
Keywords: Diversity, hotspots, flora census, distribution, Red list taxa
HOLLENBACH, M. & al., Fire ecology and management of Eucalyptus loxophleba woodlands in Western Australia, S. 133-153
Abstract: Woodlands dominated by Eucalyptus loxophleba were largely cleared in the Western Australian Wheatbelt. Today, fragmented remnants occur, which are threatened by disturbances and are lacking regeneration. There is little knowledge about these ecosystems and no active management approach beyond removing artificial disturbances. Semi-natural habitats, that allow studying their natural ecology, are only found at the distributional margins like in the Charles Darwin Reserve, a private nature reserve of Bush Heritage Australia. There, E. loxophleba woodlands were assessed for their population dynamics in order to find out about critical processes in the life cycle as basis for an active management scheme to sustain these woodlands in perpetuity. The assessment was done by representative transects through the woodlands, recording position and attributes of trees, and associated vegetation. The crucial role of fire became soon apparent and fire was discussed as management tool for E. loxophleba woodlands.
Keywords: reproduction strategy, population dynamics, age classes, York gum, Charles Darwin Reserve
KÜHN, I., Die floristische Kartierung – ein heißes Thema, S. 154-165
Abstract: The importance of floristic mapping for the analysis of urgent scientific questions is highlighted and first results of scenarios of climate change impacts on the German flora are presented. Under moderate climate change, 60% of the species lose more range than they gain; 7% lose more than 2/3 of their current range. Under a severe climate change scenario, 68% of the species lose more range than they gain; 20% lose more than 2/3 of their range. All scenarios yielded a decrease in German plant species diversity. Climate change with a temperature increase >2 °C results in disproportionate impacts. To be more efficiently usable in the future, suggestions for future activities are given.
Keywords: climate change, Germany, mapping quality
